MACHINE FOR CUTTING- GLUE-STOCK.

SPECIFICATION forming part of Letters ratent 110.414,?66, dated November12, 1889.

Application filed January '7, 1889. Serial No. 295,618. (No model.)

To all whom it may concern.-

Be it known that I, FREDERICK J. FISCHER,

a citizen of the United States, residing at Detroit, in the county ofWayne and State of Michigan, have invented certain new and usefulImprovements in Machines for Cutting Glue-Stock, of which the'followingis a specification, reference being had therein to the accompanyingdrawings.

This invention relates to new and useful improvements in machines forcutting gluestock; and the invention consists, primarily, in thepeculiar construction and arrangement of the feeding devices by means ofWhich I 5 the stock is carried into the knives, and, further, in thepeculiar construction, arrangement, and combination of the differentparts, all as more fully hereinafter described, and specifically setforth in the claims;

In the drawings which accompany this specification, Figure 1 is avertical central longitudinal sect-ion of my improved machine, and Fig.2 is a plan view thereof.

, A represents the frame supporting the opz 5 crating parts of themachine.

B B are transverse rollers suitably journaled in the sides of the frame.0 is an endess carrier-belt passing over these rollers in thelongitudinal direction of the machine,

0 and preferably consisting of impervious belt- Ing. r

D are intermediate rollers supporting the upper portion of thecarrier-belt between the rollers B B.

E are the sides of the frame, projecting above the carrier-belt.

F and Ft are a pair of feed-rollers at the rear end of the machine, andjournaled in suitable bearings in the sides of the machine.

H is a bridge between the lower feed-roller and the adjoining roller B,and forming with its edge I a scraper for the carrier-belt .C.

K is a transverse shaft journaled in suitable bearings at the rear endof the frame, 5 and L are a series of rotary disk-cutters secured atequal distances apart upon the shaft K.

M is a scraper-comb projecting from below into the interstices betweenthe cutter-disks. The feed-rollers F and F are studded all over theircylindrical surface by being corrugated in their longitudinal direction,and

tionary bearings, and it, is preferably larger' than the upperfeed-roller.

The shaft K of the rotary cutter-disks is secured in longitudinally-ad justable bearings to adjust the knives closer or farther away from thefeed-rollers, both of which are entered by the cutting-edges of saiddisk to the depth of.the annular grooves, or nearly so. -Motion iscommunicated to the operating parts in any. suitable manner.

The shaft K of the rotary disk serves, preferably, as a maindrive-shaft, from which the motion is carried to the other parts bysuitable intermediate gear.

In practice the machine is designed to cut up glue-stock, such as,consisting of irregular pieces of hide, forms a slimy mass. This stockis fed by the attendants under the carrierbelt at the front end of themachine. This belt, traveling in the direction indicated by the arrows,carries the stock onto the bridge, from which it is gradually drawn intothe feed-rollers, which distribute it evenly. By the feed-rollers thestock is impacted into the interstices between the studs, and therebycarried by the rollers into the path of the cutting-edges of the rotarycutter-disks, a portion of the stock being carried by the upper rollerand a portion being carried by the lower roller. By thus becoming wedgedinto the interstices between the sides of the rollers the cutting-edgesare enabled to cut the stock into small pieces without any liability ofthe knives becoming choked up or of any pieces escaping the action ofthe knives. The cut-up stock readily drops into suitable receptaclesplaced below or onto another carrier, which carries them away from themachine. The scraper-comb entering the interstices between the disks isarranged to remove all thecut-up material from between said disks and toscrape it below into the receptacle or onto the floor. The upperfeedroller is journaled in yielding bearings to allow chunks of materialto pass readily through the machine without disturbing the operation.

lhe sides of the frame are made of suit able height to keep the materialupon the carrier-belt. Suitable adjustments are provided to tighten thecarrier-belt whenever it becomes necessary.

On account of the slippery and slimy condition of the glue-stock and ofthe tough nature of the material it is difficult to devise a machine ofthis kind which will work satisfactorily; but by the peculiar action ofthe feed-roller in my device I have found a positive means to feed thestock into the knives with the most satisfactory results. I make thelower roller F preferably larger than the upper roller to make the angleat which the rotary cutter-disks cutting-edges meet the material uponthe lower feed-roller as small as possible to obtain a drawing out,which gradually severs the material with the least resistance. r a

It is obvious that a satisfactorily-operating 1 machine may beconstructed with one of the feed-rollers studded only and the otherplain. This would be, however, at the expense of the capacity of themachine, as less stock would be carried into the cutters.

As the knives are ground down, they may be adjusted to the feed-rollersby means of sliding bearings, in which the shaft of the cutter-disk isjournaled. 1

WVhat I claim as my invention is- 1. In a machine for the purposedescribed, the combination, with the rotary cutter-disks andconveyer-belt, of the feed-rollers arranged one above the other betweenthe belt and the disks, with their axes parallel with that of the disksand studded, and the bridge II, arranged between the belt and therollers and serving as a scraper for said belt, substantiallyas shownand described, and for the purpose Specified.

2. In a machine for the purpose described, the combination, with therotary cutter-disks and eonveyer-belt, of the bridge 11, and thefeed-rollers arranged one above the other between the belt and thedisks, with their axes parallel with that of the disks and studded, saidrollers being of unequal diameters with the lower one the larger,substantially as shown and described, and for the purpose In testimonywhereof I affix my signature, in presence of two witnesses, this 23d dayof N ovember, 1888.
